It is possible to support Mach IPC on other operating systems, with
degraded performance and security.  For example, a shared library can
take the place of the Mach kernel.  The ports and other IPC data
structures reside in shared data.  A netmsgserver process uses the
shared library and also talks to other netmsgservers elsewhere in the
network.
